BENJAMIN F. MGG-UINESS, OF WORCESTER, MASSACHUSETTS, ASSIGNOR TOCROMPTON & KNOWLES LOOM WORKS, A CORPORATION OF MASSACHUSETTS. I

TAKE-UP MECHANISM OF LOOMS.

To all whom it may concern:

Be it known that I, BENJAMIN F. Mo- GUINEss, a citizen of the UnitedStates, residing at Worcester, in the county of VVorcester and State ofMassachusetts, have invented certain new and useful Improvements inTake-Up Mechanism of a Loom, of which the following is a specification.

My invention relates to the take-up mechanism of a 100111, and moreparticularly to a spreader, for spreading or stretching the fabric, andparticularly light and delicate fabrics of fine texture, as silk, etc.,after they are woven, to prevent them from wrinkling or creasing, whenthey are wound on the cloth-roll.

The object of my invention is to provide an improved spreader, to beused in connection with the take-up mechanism, and more particularly aspreader made in the form of a roll, which has a rotary movementcommunicated thereto preferably by the woven fabric passing over saidroll.

In my improvements I provide a spreader or expanding roll having acentral shaft, and 'a series of separate strips of wood, or othersuitable material, extending around said central shaft or journal, andin the direction of the length of the roll; and each strip separatelyattached to the central shaft or journal, and adapted to be movedlongitudinally thereon, independently of the other strips, as said rollrotates; and I provide means for automatically moving outwardly thestrips on the roll, in the direction of their length, so as to increasethe length of the peripheral surface of the roll where the fabric passesover said roll, and also means to move the strips inwardly, to returnthem to their normal position.

I have shown in the drawings a take-up mechanism of well knownconstruction and operation, with my improvements combined therewith,sufficient to enable those skilled Specification of Letters Patent.

the loom, and as it is wound on the clothroll. Fig. 2 shows, on anenlarged scale, one end of the spreader roll shown in Fig. 1, detached.3 is an end view of the parts shown in Fig. 2, looking in the directionof arrow at, same figure. Fig. 4 shows, on an enlarged scale, thespreader roll shown in Fig. 1, detached, with one of the strips at oneend drawn out, and the other end of the roll shown in section, and, Fig.5 is a cross section, on line 5, 5, Fig. t, looking in the direction ofarrow Z2, same figure.

The take-up mechanism, shown in Fig. 1

of the drawings, may be of any usual andwell known construction, andtherefore will only need a brief description. In said figure, 1 areportions of the loom sides or end frames; 2 is the breast-beam, 3 arevertically extendingstands secured at their upper ends to thebreast-beam, and at their lower ends to a transverse girt of the loom,not shown, in the ordinary way.

a is the breast-beam roll over which the woven fabric 5 passes from theloom, not shown.

6 is my improved spreader or expanding roll to be hereinafterdescribed,under which the woven fabric 5 passes from the guideroll 1 to thetake-up roll 7 From the take up roll 7, the woven fabric 5 passes overthe guide-roll 8 to the cloth-roll 9. rolls are journaled in suitablebearings in the stands 3.

10 is a ratchet wheel fast on a shaft 11, and is operated by a pawl, notshown, driven from some moving part of the loom in the usual way. Apinion 12 fast on the shaft 11, meshes with and drives a gear 13, andthrough pinion 14f drives a gear 15 fast on the shaft 7 of the take-uproll 7. On the opposite end of the shaft 7 of the takeup roll 7 is agear 16 which meshes with and drives an intermediate gear 17, which inturn meshes with and drives a gear 18 loose on the shaft 9 of thecloth-roll 9. The gear 18 is clutched to and rotates the shaft 9 of thecloth-roll 9, through a friction disk 19, or any other suitable frictionmechanism, the tension of which may be regulated by a hand wheel 20, inthe usual way.

All of said All of the above mentioned parts, except the spreader roll6, may be of the ordinary construction, and operated in the usual way.

I will-now describe my improvements in spreader or expanding roll. Thespreader or expanding roll 6 is in this instance located intermediatethe breast-beam roll t and the take-up roll 7, and the woven fabric 5passes over the underside of said roll 6, before it passes to thetake-up roll 7. The spreader roll 6 has a rotary movement communicatedthereto by the movement of the cloth passing over said roll, and saidroll acts to spread or stretch the fabric before it passes to thetake-up roll 7.

The spreader roll 6 is preferably made as shown in the drawings, andconsists of a solid central shaft or axis 6, having in this instancereduced ends forming journals, which are mounted in suitable bearings inthe upright stands 3. Extending around the central shaft 6, and formingthe peripheral surface of the roll 6, are a series of strips 6,preferably of wood, or other suitable material, in this instance eightin num ber. The outer surfaces of said strips 6" are perferably coveredwith felt, or sandpaper, or some other suitable frictional surface. Thestrips 6 are cut through their middle portions, preferably in the mannershown in Fig. 4-, so as to form two separate sets of strips 6", one forone-half of the roller, and the other for the other half. Each strip 6has one or more elongated slots or openings 6' therethrough, to receiveone or more headed screws 21, in this instance only one screw is shownfor each slot 6. Each screw 21 is screwed into a threaded hole in theshaft 6, and has its head extend over a shoulder or projection aroundthe opening 6, as shown, to hold the strip 6 in position on the centralshaft 6, and allow free longitudinal movement of said strip. The outerend of each strip 6 is provided in this instance with two outwardlyextending projections 6 thereon, with a recess between them, as shown.

To cause the positive outward movement of the strips 6", as the roll 6rotates, through the movement of the woven fabric 5 passing around thesame and on to the take-up roll 7 I provide in this instance acam-shaped finger or bar 22, which extends into the recesses between theprojecting portions 6 on the strips 6, and has its hub 22 adjustablysecured on a transverse rod 23, secured to the upright frames 3. As theroll 6 revolves, in the direction indicated by the arrow in thedrawings, the engagement of the stationary cam fingers or bars 22, ateach end of the roll 6, with each strip 6, acts to move outwardly thestrips 6 as shown, and to lengthen or expand the peripheral surface ofthe roll 6, and to cause the stretching of the woven fabric 5, as shownin Fig. 1. After the strips 6 of the roll 6, in the revolution of theroll, have passed out of engagement with the cam fingers or bars 22,their outer ends are engaged by the stationary cam or curved shapedfingers or bars 24, the hubs 24 of which are adjustably secured on thetransverse rod 23, and the strips 6 are returned to their normal inwardposition.

The operation of my improved spreader or expanding roll will be readilyunderstood by those skilled in the art. As the spreader roll 6 isrevolved by the Woven fabric 5 passing under the same and on to thedriven take-up roll 7, the engagement of the cam fingers or bars 22 withthe strips 6 of the roll 6, move outwardly said strips, and cause thespreading or stretching of the woven fabric transversely, and after thestrips 6 have passed out of engagement with the cam fingers or bars 22,they are engaged by the cam fingers 2a, which move said strips intotheir inward or normal position. The amount of outward movement of thestrips 6" of the spreader roll 6 may be varied, by adjusting the hub 22of the cam fingers or bars 22.

It will be understood that the details of construction" of myimprovements may be varied if desired. A positive rotary motion may becommunicated to the spreader roll from some driven part of the loom ifdesired.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is 1. In a take-up mechanism, a spreader forwoven fabric, comprising a shaft having a rotary movement, and having aseries of strips extending around it, and attached thereto and movablelengthwise with respect to said shaft, each strip having an elongatedslot or opening therethrough for a headed screw, and said screw, andeach strip provided at its outer end with two outwardly extendingprojections thereon with a recess between said projections, and meansfor positively moving said strips outwardly and inwardly, said meanscomprising a stationary cam finger or bar, extending into said recessesat the outer end of said strips, to move outwardly said strips and alsoa stationary cam or curved shaped finger or bar, to engage the outerends of said strips to move inwardly said strips.

2. In a take-up mechanism, a spreader for woven fabric, comprising ashaft having a rotary movement, two separate sets of strips extendingaround said shaft, one-half of said strips for onehalf of the spreader,and the other for the other half of the spreader, each strip having anelongated slot or opening therethrough for a headed screw, and saidscrew for attaching the strip to the shaft, and each strip provided atits outer end with two outwardly extending projections thereon with arecess between said projections, and means for positively moving saidstrips outwardly and inwardly, said means comprising a stationary camfinger or bar extending into said recesses at the outer end of saidstrips to move outwardly said strips, and also a stationary cam orcurved shaped 10 finger or bar, to engage the outer ends of said stripsto move inwardly said strips.
